GRE DI: Overview of Data Interpretation

Data Interpretation questions appear within the quantitative section on the GRE and usually come as one set with three questions based on the same data set. Data interpretation is not a separate question type. It is a format that presents raw information through charts and tables, which form the core of what you analyze. The question formats remain the same, including multiple choice select one, multiple choice select one or more, and numeric entry, and quantitative comparison questions generally do not appear in these sets. These questions help you read data, identify useful information, and process it to answer specific questions. These skills support strong performance across the quantitative section and connect naturally to higher order careers. For this reason, thorough coverage of data interpretation is an essential part of a sincere GRE prep course.

The following video gives a clear and thorough overview of data interpretation question types. It helps you visualize how these questions appear, what they look like, and how they show up on the GRE. Use this overview to build a strong foundation before moving deeper into data interpretation questions in the upcoming lessons. All the best!

Data Interpretation Problems on GRE

Data Interpretation problems on GRE

Data Interpretation (DI) is not a separate topic or unique question type, but rather a variation of general quantitative questions where background information is provided through graphs, charts, or tables. The core task involves identifying relevant information from these visual aids, filtering out unnecessary data, and processing the useful points to answer specific questions.

Key Skills Required

Macro-data Understanding: The ability to grasp the overall context of the information presented.
Data Point Identification: Pinpointing the exact values needed to solve a specific problem.
Data Utilization: Converting raw data into a structured format to reach a final answer.

Core Academic Concepts Tested

DI problems frequently evaluate proficiency in the following mathematical areas:

Percentages: This includes calculating specific percentages, as well as determining percentage change versus absolute change.
Ratios: Comparing different quantities derived from the data sets.
Statistics: Calculating and interpreting the Mean, Median, Mode, Range, and Standard Deviation.
Probability: Determining the likelihood of events based on the provided data distribution.

Data Interpretation on GRE: What to Expect?

The GRE Data Interpretation (DI) component primarily consists of one comprehensive set of questions based on a specific visual prompt. This prompt typically features either a single graphic or two interrelated graphics, such as tables, charts, or graphs.

Structure of the DI Set

Question Count: Each set contains 3 specific questions.
Location: This set is generally encountered during the first Quantitative section of the exam.
Question Formats: The questions are drawn from four specific types:

- Multiple-choice questions where you select exactly one answer.
- Multiple-choice questions where you select one or more answers.
- Numeric Entry, where you type in a specific value.
- Quantitative Comparison, where you evaluate the relative size of two quantities.

Additional Appearances

Beyond the main set, you may encounter standalone questions that are chart-based. The analytical skills required for the primary DI set are directly applicable to these individual questions.
